Experienced bodybuilders know that increasing muscle size and strength requires PTA— pain, torture and agony. As Governor Arnold said in “Stay Hungry,” his first mainstream movie, “You must burn to grow.” Japanese researchers showed that beginners benefited from low-intensity, slow-movement weight training.
Two groups of untrained young men lifted weights for 12 weeks, training either at a normal cadence using higher resistance (80 percent max effort) or a slow cadence (3 seconds up, 3 seconds down) and low intensity (50 percent max effort).
The men in both groups gained equal amounts of strength and muscle mass compared to control subjects who didn’t exercise. This study showed that beginners respond to low-tension, slow movement weight-training programs, but the results do not apply to trained bodybuilders.
